Hi there,

I need to adjust the columns in a scripted DataSource at designtime. This works perfectly as long as I do not include my own libary.

At describe event of the datas source:
This works:

This does not work:

As you can see, I don't even use "myVariable". The import seems enough to make the designer not to show my columns in the tree at Data Explorer. When I preview the columns (Properties->Preview Results) everything is ok and it works, so its not a general problem. But I need the columns in the tree at the Data Explorer at design to use them. This is filled in the first case, but empty in the second one.

Thanks for any help.
